CleanMyOwn 1.0

Native macOS cleaner and maintenance app, built in SwiftUI. Junk caches, orphaned app data, large files and duplicates, uninstalling apps with their leftovers, login items, and live memory pressure — no Electron, no always-on daemon, no telemetry.

Requirements

• macOS 14 or later
• Apple Silicon (arm64) — this build is not universal, so it will not run on Intel Macs

Install

Open the .dmg and drag CleanMyOwn to Applications.

First launch

This build is ad-hoc signed and not notarized, so Gatekeeper will refuse it on first open with a message about an unidentified developer. To run it anyway:

1. Right-click (or Control-click) CleanMyOwn in Applications → Open → Open.

If macOS still blocks it, clear the quarantine flag:

xattr -dr com.apple.quarantine /Applications/CleanMyOwn.app

Because the build carries no stable signing identity, the Full Disk Access grant does not survive a reinstall — you will need to grant it again after replacing the app.

Notes

Privileged work runs through a session-scoped AuthorizationRef, or an optional SMAppService helper limited to four allowlisted verbs. See the README for the architecture and the reasoning behind it.
